To all 'whom it may concern.'

Be it known that I, FRANK WALLERTZ, a citizen of the United States, andA a resident of the city of Chicago, in the county. of

Cook and State of Illinois, have invented certain new and useful Improvements in Containers, of which the following is a' adapted for use 1n packaging commoditiesfor ready sale to the consumer.

The principaly object of my invention is the provision of a container thatis capable of being readily assembled so that the capacity thereof will be certain and uniform,

and to this end I provide 'a novel blank wherein are provided suitable interlocking orcoacting elements that are adapted to predetermine the diameter or capacity of the finished structure so 'that the user will experience no trouble in arriving at the proper size.. 'Ihis also permits the manufacturer to ship a quantity of knocked down structures in considerably less space than that occupied by finished or assembled containers, thus enabling a material reduction in the price of \the 4containers to be made to the user. Another objectlis the provision of a container blank having facilities for positioning'or more firmly securing the top and bottoms therein. Other objects will be obvious after an understanding of my in vention is had from the following explanation and accompanying drawings.

I prefer to accomplish the divers objects of'my invention in substantially the manner hereinafter described and as more particularly pointed out in the appended claims.

And I desire to statethat while I have illustrated and described two types of structures herein there are many ways of carryingout my invention, the present drawings being ina sensemerely diagrammatic for the purpose of convenience in illustrating the prin-4 ciples of my invention.l

In the drawings similar reference characters have been employedin the respective views to designate the same parts, and in said drawings,-

Figure v1 is a central vertical sectionrof a cylindrical container made in accordance with the principles of my invention.

4from which the cylindrical body of said container is fabricated.

Fig. 3- is a view similar to Fig. 1, of a conical or tapered container, of a slightly modiied construction, but also embodying the principles of my invention.

Fig. 4 is a p lan of the blank or pattern from which the tapered body of the container structure illustrated in Fig. 3 is fabricated.

Referring to Fig. 2, it will be observed this particular blank or pattern preferably comprises an elongated rectangular shaped strip 5, of suitable tissue, such as a brous paper stock or the like, having a portion 6,- that isreduced in its transverse dimensions by cutting away elongated strips from the `longitudinal edges, as shown, the purpose of which will hereinafter be fully explained. The transverse 'end edge 7 of the reduced portion of the blank is provided with a transverse tongue 8 for the purpose of coacting or entering a transverse slit 9, cut inwardly from one of the longitudinal edges of the blank, preferably at a right angle to llienldge of the narrower portion of the The slit 9 is positioned a distance from the' tongue 8, so as to predetermine the diameter ofthe interior of the container, so that the container may be correctly assembled by unskilled persons, simply by inserting the tongue 8 through the slit 9, and then rolling the remainder of the blank around the cylinder thus formed. The outer or end edge 10 of the strip is secured down ,against the cylinder by stapling or by treatment with an adhesive substance to prevent its letting loose. When the cylinder has been thus formed, it will be found that the narrower portion 6 `of the blank which has been rolled inside the cylinder will provide `a shoulder 11 adjacent each open end of the cylinder, so that-the bottom and top end caps 12 and 13, respectively, may be inserted into the ends and brought into engagement with said 'shoulders 11,'as shown. These end caps are each provided with peripheral flanges 152a and 13, respectively, and after said caps have been positionedthe edges 5a of the Wide portion of the blank are turned in oyer .the flanges and preferably crimped or otherwise-pressed into position to'A securelyl'seal the container. In making certain con-` a top end cap 13, that is provided with a" central opening 14, as shown in Fig. 1, and

in this event I prefer to close the top of the container with a disk 15, that is inserted over the cap 13,'either before or after the edge 5a has yb'een seamed and secured in ace. In Fig. 3 the container is of conical or tapered shape, so that after assembly the empty vessels may be nested, thepone in the other, and thus occupy less storage space than the .cylindrical type of container heretofore described. The blank or pattern for fabricating the conical or tapered container is of segmental or curved shape, as illustrated in Fig. 4, the body portion 20, which comprises the inner layer of the wall of the finished container being narrower than the remaining portion 21, which comprises the outer-,layer of the wall thereof. `In lieu of the single tongue 8, shown on the cylindrical container, I may employ tongues or extensions 22, that continue from the upper and lower edges of the body 20, as shown, and at the proper predetermined points I make short transverse slits 23, that are cut inwardly from the upper and lower edges of the blank.' The assembly of this tapered containeris similar to that f the cylindrical structure and consists of inserting the tongues or extensions 22 through theirrespective slits 23, which determine .the diameter of the container, and then wrapping the remaining wider portion 21 of the 'blank around the structure ,thus formed, and securing the end-edge 24 in place. The top and bottom end caps-25 and 26, respectively, are inserted in thelr positions upon the shoulder 27, formed by the edges of the narrow body 20 of the blank, after which the edges 21a are turned over and crimped outside the `caps, thus securing the latter in place and closing the container.

In both of the structures it will be noted 'the tongues or extensions 8 and22 will-be positioned between 4the inner and outer layer or wrapping of the blank forming the coni Itainer, so that the liability of their withdrawal is avoided, and the blanksbeing previously cut and slitted, at 9 and 23, no trouble will be experienced/by the unskilled mechanic in determining fthe diameters of the containers, as this has been prede- 4 termined at the factory making the blanks.

The presence of the tongues and slits, .as herein .described not only ermits positive determination of 'the interior diameter ofl the container, but also further acts, when `the containers are. in final form, to `prevent any skippin between the respective layers which woul result not only in changing the interior diameter, but in destroying the integrity of the structure as a whole. It will also be observed the blanks may be cut in large quantities, put up in packages and shipped, knocked-down, to the users, thereby utilizing considerably less space in ship-v 1. A container comprising an elongated blank having a reduced portion, and provided with a transverse slit, a tongue adjacent one end of said blank that is inlserted in said slit to provide a structure of predetermined diameter, the remaining portion of said blank adapted to be'wound concentrically about and be secured to the initial structure whereby shoulders are formed within the container adjacent the ends thereof and said tongue is secured between the inner and Louter layers of said blank, closure caps seated on saidshoulders and the widerportions of said blank forming the outerlayer of the structure adapted to be turned over above said caps and secure the latter in place.

2. A container comprising an inner and outer wall, one of said walls being' provided with a transverse slit extended inwardly from the edge of the blank of which thecontainer is fabricated, the -outer wall being wider than the inner wall and adapted to be turned over at'the ends of the container,

and a tongue adjacent the end of the inner wall adapted to lbe inserted in the above mentioned slit and be secured between the inner and outer walls whereby-5a container of predetermined diameter is Provided.

3. A container comprising .an elongated blank having a reduced portion andr provided with a` transverse slit extended 'mwardly from one longitudinal ed'e of the blank, a ,tongue adjacent one en of said blank, said container adapted to be formed lvwith an inner and outerl wall,` the inner wall formedlby coiling4 the tongue end of thel blank and inserting said tongue through said slit so that the former is disposed upon the outer side of the inner wall, and the outer wall formed by continuing to coil the wider" portion of said blank upon the inner wall structure and securin the same tothe outside of said inner wa whereb said tongue etween said edge thereof, a tongue adjacent one end of said blank, said 'container adapted to be l.formed with an inner and an outer wall, the inner wall formed bv coiling the tongue end of the blank and inserting said tongue through said slit so that the outer wall is formed by continuing to coil the remaining portion of said blank upon the inner 'Wall structure and. securing 'the same to the outside of Said-inner-WaIl Wherebysaid tongue is securely held in position between Seidl Walls.
